It is assumed that the WebIOPi user is "pi"
Copy the attached shell script (ds2482.sh) into your home directory (/home/pi)
Make it executable (chmod 755)
You can call it manually (sudo ./ds2482.sh) if you don't need automated start at boot
To get it started automatically at boot, insert the following lines at the end of /etc/rc.local just before the last line which is "exit 0" (e.g. with "sudo nano /etc/rc.local"):
Load 1-wire DS2482 master kernel drivers
sudo bash /home/pi/ds2482.sh
Reboot
As example, I have also attached a rc.local file, yours may contain additional instructions.
To finish or disable the automatic loading, delete the lines or comment them out.

Additional info:
If you only use a 2482 and/or use GPIO 4 without a pullup resistor, delete line 3 from the script (it loads w1-gpio with the pullup parameter), you don't need it.
I did not test so far what happens when having multiple 2482 chips on the I2C bus using different I2C slave addresses for them and having multiple tee-commands in the script. So for the time being, use the 2482-800 for 1-wire multi channel architectures, it was tested and worked and gives you 8 separate 1-wire channels.
